Check Digit Verification of cas no
The CAS Registry Mumber 6054-81-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,0,5 and 4 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 6054-81:
(6*6)+(5*0)+(4*5)+(3*4)+(2*8)+(1*1)=85
85 % 10 = 5
So 6054-81-5 is a valid CAS Registry Number.
